The white paper describes what is meant by aggregated data.
In the context of life cycle assessments aggregation means to trace back process data to elementary material flows and to compress the data into a single list of inputs and outputs.
Elementary flows are all substances, originating from environment (e.g. crude oil, minerals) and being emitted into the environment (e.g. CO2, NOx). Aggregated data describe single processes or an average of various equal processes.
Hurricanes Ivan, Katrina, and Rita passed through the Gulf of Mexico during 2004 and 2005 and resulted in the largest number of destroyed and damaged offshore structures in the history of Gulf operations. In the final official government assessment, a total of 120 platforms were destroyed and over 183 structures were identified as having extensive damage. One deepwater floating structure, Chevron's mini tension-leg platform Typhoon, was destroyed. According to Minerals Management Service production data, 21...
Scale formation is one of the most serious oil field problems that inflict water injection systems primarily when two incompatible waters are involved. Two waters are incompatible if they interact chemically and precipitate minerals mixed. Due to the lack of reaction kinetics data, the rate of strontium sulphate deposition in porous rock was measured through flooding sandstone core samples of uniform properties with supersaturated brine. The brine was formulated at the core inlet by mixing of injected sea water...
Quality Assurance Solutions, LLC (QAS), has been using Mint Miner to review environmental testing data since 2003.
“I believe strongly in this product and give out demo copies to every client I meet,” says Diane Lawver, President of QAS. “The product is well-designed and focused on the issues around assuring the integrity of organics data used for decision-making.”
QAS uses Mint Miner to conduct quality system audits and evaluate data integrity issues in environmental testing samples. The reports generated by...
Abstract Sodium N-methyldithiocarbamate (metam sodium) and 1,3 dichloropropene are widely used in potato production for the control of soil-borne pathogens, weeds, and plant parasitic nematodes that reduce crop yield and quality. Soil fumigation with metam sodium has been shown in microcosm studies to significantly reduce soil microbial populations and important soil processes such as C and N mineralization. However, few published data report the impact of metam sodium on microbial populations and activities in...
Introduction
Many businesses now use systems that work in real time for acquiring, storing, analyzing and issuing data in all their plants in an efficient manner. These real time archiving systems enable you to obtain data with the aid of sensors and electronic control panels directly and quickly. These real-time acquisition systems store crucial data on operations carried out within the company as well as the state of its manufacturing processes. The aggregation of data thus enables you to carry out an analysis...
ABSTRACT
Market-based system delimitation may reduce the need for data collection in life cycle assessments (LCAs) without compromising reliability. Rather than including all potential suppliers and customers (e.g. in a weighted average), the market-based procedure allows the data collection to be reduced to those suppliers and customers, which are actually affected by a studied product substitution. Furthermore, the uncertainty on the market data will most often determine the level to which the overall uncertaint...
In the spirit of the material recycling concept in Germany (KrW-/AbfG, 1994), wastes are to be recycled as completely as possible, avoiding any impairment for mankind and the environment. In this connection, avoidance of material burdens by excessive nutrient and pollutant discharge is particularly important in the treatment, recycling and bringing into circulation of waste materials for re-use in agriculture and forestry, as well as in horticulture and landscape conservation/recultivation. The implementation of...
Introduction & Background
Aim and scope of the report
This report, aimed at both individual companies and organisations representing company stakeholders and policy-makers, summarises current trends, problems and developments in the areas of Environmental Performance Indicators (EPIs); Environmental Reporting; Environmental Performance Ranking; and their interconnections as a contribution to enhancing the eco-efficiency of companies. There is also a supplementary report focusing on environmental reporting...
